As shown in (A), the tip of the support positioning projection 55 that abuts the upper surface of the game control circuit board 92 and penetrates the locking hole 96 engages with the hole formed in the center of the pressing member 76. Since they match, one long side of the game control circuit board 92 is clamped and fixed by the support positioning projection 55 and the pressing member 76, and the other side long side is completely fixed by the screw 95. The control circuit board 92 is fixed in the board storage box 50.

By the way, the cover body 70 is formed with a separation cover body portion 80 which constitutes an essential part of the present embodiment. The structure of the separation cover body 80 will be described in detail below mainly with reference to FIG. The separation cover body portion 80 has a rectangular shape and is provided at a corresponding position in the upper portion of the ROM 98 mounted on the game control circuit board 92, and two pieces are connected in a bridge shape at appropriate positions in the longitudinal direction. The cover body 70 and the separation cover body portion 80 are integrally formed by the protrusion 81 (in the present embodiment, integrally formed of synthetic resin). And the connecting protrusion 8
The separation cover body portion 80 can be completely separated from the cover body 70 by cutting 1 with a tool such as a nipper. In addition, engaging claws 82 are provided on each of the four sides of the separation cover body 80 so as to project upward. The engaging claw 82 is formed by cutting the connecting projection 81 to separate the separation cover body 80 and inspecting the ROM 98 at the time of sample inspection, and then the separation cover body 80 again.
It is used when the sheet is turned over and attached to the cover body 70. A mounting locking projection 83 is formed on the left and right of the protruding position of the engaging claw 82.

When the connecting projection 81 is cut to separate the separating cover body 80, a rectangular separating opening edge 84 is formed on the cover body 70. The separating opening edge 84 is appropriately formed. Engagement protrusions 85 that engage with the engagement claws 82 when the separation cover body portion 80 is turned upside down and attached are formed at the locations, and the placement locking protrusions are provided on the left and right sides of the engagement protrusions 85. A mounting contact protrusion 86 is provided so as to contact the piece 83.

Further, the separating cover body portion 80 is integrally formed with the cover body 70 as described above, and in this state, it is connected by the connecting projection 81, and in the connected state, the inside of the cover body 70 is separated. An inner sealing seal 87 is attached to the side surface so as to be bridged between the separation cover body portion 80 and the cover body 70. The inner sealing seal 87 has a structure in which the sealing mark 87a remains on the separation cover body 80 side when the separation cover body 80 is separated. It should be noted that a large number of heat dissipation holes 89 (the range indicated by the chain double-dashed line in FIG. 1) are formed on the surface of the separation cover body 80, and instructions for cutting the connecting projection 81 are formed. There is formed a display area 90 and a cut portion display portion 91 indicating a cut portion.

In the substrate storage box 50 configured as described above, since the box body 51 and the cover body 70 are firmly adhered by the adhesive, the box body 51 and the cover body 70 are separated and the game is played. It is impossible to release the covering state of the control circuit board 92. Then, if it is desired to release the covering state, the connecting projection 81 shown in FIG. 4A is cut along the line BB with a tool such as a nipper to separate the separation cover body portion 80 from the cover body 70. The ROM 98 must be separated to face it. However, when the connecting protrusion 81 is cut in this way, the connecting protrusion 81 disappears as a result of the cutting, and even from this point alone, whether the ROM 98 of the game control circuit board 92 has been subjected to unauthorized processing or not. Recognize.

Even if the cut connecting projection 81 is cleverly adhered with an adhesive to restore the original state, when the separation cover body 80 is separated, it is attached to the inside of two opposing places. At least one of the inner sealing seals 87 must be peeled off. When the inner sealing seal 87 is peeled off, the sealing mark 87a remains on the separation cover body 80 side. 87
It is impossible to carry out the work of adhering the connecting projection 81 with an adhesive while matching and.

That is, in the present embodiment, in the board storage box 50 for storing the game control circuit board 92 provided in the gaming machine, the board storage box 50 stores the game control circuit board 92 in the box body 51 and the box. The transparent plate 61 for closing the bottom opening 53 of the body 51, the cover body 70 for covering the upper surface of the box 51, and the like are assembled by a plurality of components, and an assembly structure for covering the game control circuit board 92. Of the box body 51 and the cover body 70 that are parts, a separation cover body portion 80 that constitutes a part of the cover body 70.

In order to release the covering state of the game control circuit board 92 by 70, there is no method other than cutting and breaking the connecting projection 81 of at least the separation cover body 80. If the connecting projection 81 is broken and the inner sealing is performed. If the sealed state by the seal 87 is released, it can be immediately known that illegal processing has been performed.

If the connection projection 81 is carefully cut and the game control circuit board 92 is illegally processed,
It is conceivable that the cut connection projection 81 is bonded by an adhesive or the like to disguise it as if fraud was not made. However, even in such a case, the separation cover body portion 80 and the cover body 70 are separated from each other. It is impossible to disguise the inner sealing seal 87 that is stuck so as to be hung on the inside (interior of the board storage box 50) while returning to the original stuck state, and in the end, the game control circuit board It is easy to see whether or not the fraudulent processing for 92 has been performed.

In this second embodiment, as shown in FIGS. 5 and 8, the separation cover body portion 80 is connected to the cover body 70 by the connecting protrusion 81, as shown in FIGS. It is in a state of being sealed by the sealing seal 87. In such a state, when the first inspection is required, a plurality of (four) connecting protrusions 81 are cut by a tool such as a nipper along the line FF in FIG. As shown in, the separation cover body portion 80 can be separated from the cover body 70, and the ROM 98 can be exposed to the outside. Then, after the ROM 98 is extracted and inspected, the ROM 98 is inserted again at a predetermined position, and thereafter, as shown in FIG.

Since the mounted abutting protrusion 86b is abutted in a superposed state,
The separation cover body 80 is prevented from falling inside.

In this state, as shown in FIG.
In the center of the separation cover body 80, the display area 90a in the initial state is displayed upside down, and the cut portion display portion 91a that clearly shows the cut portion is also displayed upside down. Further, in this covered state, the inspected sealing paper 88 of the supervisory authority is pasted again from the upper surface of the separation cover body portion 80 to the side surfaces of the cover body 70 and the box body 51.

Next, a substrate storage box 50 according to the third embodiment will be described with reference to FIGS.

FIG. 17 is a cross-sectional view taken along line HH of FIG. 14, FIG. 17 is a cross-sectional view for explaining a state when the covering state is released for inspection, and FIG.
It is sectional drawing cut | disconnected by the II line of FIG.

Therefore, the difference between the third embodiment and the first embodiment is that a plurality of (4
However, in the third embodiment, a mounting piece 105 having a stop hole 105a is formed in the separation cover body portion 80 in place of the engagement nail 82, and the cover body 70 is formed. The point is that the fastening boss 106 having the fastening hole 106a is integrally formed on the back surface at an appropriate position along the separation opening edge 84 of FIG. The configuration other than this is almost the same as that of the first embodiment.

In the third embodiment, as shown in FIGS. 14 and 16, the separation cover body portion 80 has the cover body 70 by the connecting projection 81 in the state where the cover body 70 is installed in the game hall.

In such a state, when the first inspection is required, a plurality of (four) connecting projections 81 are cut by a tool such as a nipper along the line JJ in FIG. As shown in, the separation cover body portion 80 can be separated from the cover body 70, and the ROM 98 can be exposed to the outside. Then, after the ROM 98 is extracted and inspected, the ROM 98 is inserted again at a predetermined position, and then, as shown in FIG.
Is turned over and the attachment piece 105 and the fastening boss 106 are aligned with each other. Since the mounting hole 105a and the mounting hole 106a are aligned with the mounting piece 105 and the mounting boss 106 aligned,
By screwing the screw 107, the separation cover body portion 80 can be put into a covered state again.

In this state, as shown in FIG. 15, the separation cover body portion 80 and the cover body 70 are flush with each other and the head of the screw 107 projects when the screw 107 is screwed into the retaining hole 105a. I ’m not going to do that,
Sealed paper 8 which has been inspected by the authorities to cover the screw 107
8 can be attached from the upper surface of the separation cover body portion 80 to the side surfaces of the cover body 70 and the box body 51 without being damaged. With such a configuration, the separation cover body portion 80 cannot be separated from the cover body 70 unless the inspected sealing paper 88 is damaged, and thus it is possible to easily find out whether or not there is an illegality. .

When the inspection is required again, the separation cover body portion 80 can be separated by peeling the sealed sealing paper 88 and loosening the screw 107.
After the inspection, the separation cover body portion 80 may be screwed again with the screw 107 and a new sealed sealing paper 88 may be attached. And
By repeatedly performing such an operation, it is possible to perform the sample extraction inspection as many times as necessary.

Although the second and third embodiments have been described above, in the second and third embodiments as well, in the initial state, as in the first embodiment, the box body 5 is used.
In order to release the covering state of the game control circuit board 92 by 1 and the cover body 70, there is no method other than cutting and destroying at least the connecting projection 81 of the separation cover body 80. If the connecting projection 81 is broken. If it is done and the sealed state by the inner sealing seal 87 is released, it can be immediately known that the illegal processing has been performed. If the connection projection 81 is carefully cut and the game control circuit board 92 is illicitly processed, the cut connection projection 81 is adhered with an adhesive or the like to prevent illicitness. However, even in such a case, the inside that is attached so as to be hung on the inside (the inside of the substrate storage box 50) between the separation cover body 80 and the cover 70. Seal seal 8
It is impossible to disguise 7 while returning it to the original attached state, and in the end, it is possible to easily know whether or not the game control circuit board 92 has been illegally processed. In addition to this effect, there is also an advantage that the sample extraction test can be easily performed multiple times. The first to third embodiments described above
In the embodiment, the inspected sealing paper 88 is shown attached to one place, but it may be attached to a plurality of places.

By the way, the above-mentioned first to third embodiments
In the embodiment, the configuration in which the box body 51 and the cover body 70 cannot be separated by adhering them with an adhesive has been described, but another configuration is adopted as a structure in which the box body 51 and the cover body 70 cannot be separated. Is also good. For example, as shown in FIG. 19, once penetrating through a through hole formed in the cover body 70 and protruding upward, it is bent into a U-shape to be integrally connected to the upper surface of the cover body 70 and to the tip. A locking protrusion 70a having a claw portion is formed on the cover body 70, on the other hand, an upper surface thereof is an inclined surface and a lower portion thereof is an engaging surface cut acutely. When the cover body 70 is integrally formed with the box body 51 and the cover body 70 is mounted from above the box body 51, the claw portion of the locking hanging piece 70a is engaged with the engaging surface of the locking protrusion 51a. In order to prevent the combined state from being released, the locking protrusion 51a and the locking hanging piece 70
A and rivet 108 may be fixed to each other.

Here, the locking protrusion 51a and the locking hanging piece 70
The method of fixing a and a by the rivet 108 will be described. The rivet 108 used in the present embodiment is called a blind rivet 108. The rivet 108 is made of an aluminum rivet 108 and has a rivet 10 at one end.
8 has an engaging portion 109a which cannot be inserted through the inner peripheral cylinder, and a pulling pin 109 having a bent portion 109b having a small diameter is inserted into the base portion of the engaging portion 109a. Then, the blind rivet 108 is inserted into the through hole in which the locking protrusion 51a and the locking hanging piece 70a are aligned, and in that state, a pulling pin 109 is pulled in the arrow direction shown in FIG. And the rivet 108 by the engaging portion 109a.
Of the rivet 1 is deformed as shown in FIG. 19 (B).
08 and the deformed end completely lock the protrusion 5
1a and the locking hanging piece 70a are sandwiched, and then the pulling pin 109 is pulled more strongly to break the bent portion 109b and separate the tip end portion.

In such a state, it is impossible to release the pinched state of the rivet 108 from the outside of the substrate storage box 50.
The cover body 70 cannot be easily removed from the box body 51 after attaching the to the box body 51 and fixing the rivet 108. Then, if you try to remove this, the locking hanging piece 7
It is necessary to cut the base portion of 0a with a nipper or the like to separate the locking hanging piece 70a from the cover body 70. Therefore, if the base portion of the locking hanging piece 70a is damaged, an illegal act has been performed. It is immediately understandable.

In the above-described embodiment, as the fixing means, the locking projection 51a formed on the box body 51 side and the locking hanging piece 70a provided on the cover body 70 are attached to the rivet 10.
Although the structure of fixing by 8 is shown, it is conceivable to use a welding technique as another fixing means. Therefore, a fixing structure of the box body 51 and the cover body 70 by welding will be described with reference to FIGS. 20 to 26. 20 to 2
2 is a schematic cross-sectional view showing various structures when welding the box body 51 and the cover body 70, FIG. 23 is a schematic view showing the principle of the ultrasonic plastic welding apparatus, and FIG.
FIG. 26 is a plan view of the substrate storage box 50B in which the box body 51 and the cover body 70 are fixed to each other by using another welding structure.
[Fig. 26] is a partial plan view and a sectional view of a welded portion, and Figs. 26 and 27 are sectional views showing a similar welded structure.

Therefore, in the welding structure shown in FIGS. 20 to 22, the welding projection 110 extending in the horizontal direction is extended from an appropriate position on the upper side of the box 51, and the cover 70 corresponding thereto is also provided. Extend the welding projection 111 in the horizontal direction,
When the cover body 70 is fitted to the box body 51, the welding protrusions 110 and 111 are in contact with each other, and the contact portions are welded by the ultrasonic plastic welding device. Notches 110a and 111a are formed at the bases of the welding projections 110 and 111, so that the welding portions can be easily bent and separated during inspection or the like.

Now, the principle of the ultrasonic plastic welding apparatus will be briefly described with reference to FIG. 23. The receiving jig 121 is placed on the base 120, and the welding object 122 is placed on the receiving jig 121. , Above the weld deposit 122,
A horn 123 is located, and an ultrasonic vibrator 124 that applies ultrasonic vibration is connected to the horn 123, and a cylinder 125 that applies pressure to the horn 123 is connected. An ultrasonic oscillator controlled by a control unit is connected to the ultrasonic vibrator 124, and the cylinder 125 is controlled by a pneumatic control circuit.

When the start switch 126 provided on the base 120 is operated to operate the apparatus,
Ultrasonic vibration is generated in the horn 123 and the horn 1
A predetermined pressure is applied to 23 to pressurize the deposit 122. Then, in the pressurized state, frictional heat is generated on the boundary surface of the welded material 122, and the boundary surface is instantaneously welded by the frictional heat. The base 120 is provided with an emergency switch 127 that stops the operation of the device in an emergency.

By welding the welding projection pieces 110 and 111 using the welding device having the above-described operation principle, the box body 5 is formed.
1 and the cover body 70 cannot be separated unless the welded portion is destroyed. Therefore, the box 51
In order to take out the game control circuit board 92 housed inside by separating the cover body 70 and the cover body 70, there is no method other than bending and separating at least the cut portions 110 and 111a of the welding portion, and the welding portion is temporarily bent and separated. If so, it can be immediately known that the illegal processing has been performed.

When welding, as shown in FIG. 20, by forming a conical protrusion 111b on the lower surface of the welding protrusion 111 of the cover body 70, the welding time can be extremely shortened. , Melted protrusion 111b
Serves as a filling margin for filling the boundary surface, and sufficient welding strength can be obtained. In addition, as shown in FIG.
A columnar protrusion 111c is formed on the lower surface of the protrusion 11, and the welding protrusion 110 has a fitting hole 1 having a diameter slightly smaller than the diameter of the protrusion 111c.
By forming 10b and welding them while pressurizing them, the protrusion 111c is fitted and welded in the fitting hole 110b, and sufficient welding strength can be obtained in the same manner as above. Similarly, in order to obtain sufficient welding strength, the welding protrusions 110, 11
By making the tip shape of the horn 123 of the device as a corrugated protrusion 123a as shown in FIG. 12 instead of making a special effort on the 1 side, the welding recess 113 can be formed in the welding portion after welding. Sufficient welding strength can be obtained also by the welding recess 113.

Further, in the above-described embodiment, the welding projection piece 1
The cutout portions 110a and 111a are formed on the base portions of the reference numerals 10 and 111 to facilitate bending.
When applied to the substrate storage box 50 of the embodiment,
Since it is not necessary to make the welding projections 110 and 111 easy to break, it is not necessary to form the cutouts 110a and 111a, and the welding projections 110 and 111 are provided over the entire circumference of the box body 51 and the cover body 70. You may form and weld these.

Next, the structure of the substrate storage box 50B according to another fixing structure which is similarly fixed by using the welding technique will be described with reference to FIGS. In this substrate storage box 50B, rectangular through holes 130 are formed at appropriate positions (three positions in the drawing) on the outer peripheral edge of the cover body 70, and inclined surface portions 131 that are inclined toward the through holes 130 are provided around the through holes 130. Further, a guide piece 134 is provided around one side of the back surface of the through hole 130, while a protruding piece 132 having a rectangular cross section is provided on the box body 51 so as to penetrate the through hole 130. Then, as shown in FIG. 25C with the protruding piece 132 penetrating the through hole 130 along the guide 134 piece, as shown in FIG. By welding and engaging the inclined surface portion 131, the box body 51 and the cover body 70 cannot be separated from each other unless the welding portion 133 is broken. Therefore, in order to take out the game control circuit board 92 housed inside by separating the box body 51 and the cover body 70, there is no method other than at least destroying the welded portion 133, and the welded portion 133 is temporarily destroyed. If so, it can be immediately known that the illegal processing has been performed.

In this welded structure, the welded portion 1
The base portion of 33 (that is, the base portion of the protruding piece 132) is cut cleanly to separate the box body 51 and the cover body 70, and a fraudulent act is performed. Then, an adhesive is applied to the cut surface and the box body 51 is removed again. Since there is a possibility of fraudulent assembly with the cover body 70, as shown in FIG.
If a crime prevention guide piece 135 is also provided on the other side of the back surface of 0, the above-mentioned fraudulent acts can be prevented.

Further, the shapes of the protruding piece 132 and the through hole 130 may be changed. For example, as shown in FIG.
Without forming a through hole in the cover body 70, the protruding piece 1 of the box body 51
36 is formed in a crank shape to receive the cover body 70, the tip of the crank-shaped protruding piece 136 is welded to the inside by a horn 123 having a semicircular tip shape, and the cover body 70 is attached to the welded portion 137. You may comprise so that it may be wrapped. Further, as shown in FIG. 27, the protruding piece 1 is formed without forming an inclined surface portion around the through hole 130 of the cover body 70.
When 32 is projected, the shape of the horn 123 may be formed in a Fuji shape, and the tip of the protruding piece 132 may be divided into two forks to form the welding portion 138 for covering and welding the upper surface of the cover body 70.

Since the inner sealing seal 87 as the demonstrating means for clearly indicating the covering state is provided and the inner sealing seal 87 as the demonstrating means is provided inside the substrate storage box 50, the game by the box body 51 and the cover body 70 is performed. Control circuit board 9
To release the covering state of No. 2, there is no method other than cutting and breaking at least the connecting projection 81 of the separation cover body 80. If the connecting projection 81 is broken and the sealing state by the inner sealing seal 87 is If it is canceled, it can be immediately known that illegal processing has been performed. However, after carefully cutting the connecting protrusion 81 and performing an illegal process on the game control circuit board 92, the disconnected connecting protrusion 81 is adhered with an adhesive or the like so that the illegal operation is not performed. However, even in such a case, the inside that is attached so as to be hung on the inside (the inside of the substrate storage box 50) between the separation cover body 80 and the cover 70. It is impossible to disguise the seal 87 while returning it to the original attached state, and in the end, the game control circuit board 92.
It is easy to know whether or not the fraudulent processing has been performed for.

Further, as an area range of the above-mentioned separation cover body 80, a ROM provided on the game control circuit board 92.

As is apparent from the above description, in the present invention, in the board storage box for housing the circuit board provided in the gaming machine, the board storage box includes a plurality of constituent parts including the circuit board. The fixing means that cannot be released from the covered state unless the predetermined portion related to the assembled component for covering the circuit board is destroyed and the released state is clearly shown. Explicit means is provided, and moreover,
Since the indicating means is provided inside the board storage box, there is no method other than destroying at least a predetermined portion to release the covering state of the circuit board by the assembled component. If there is a statement that the destruction has been made by the explicit means, it can be immediately known that the illegal processing has been performed. However, it is conceivable that the prescribed part should be carefully destroyed to improperly process the circuit board, and then the destroyed part should be bonded with an adhesive or the like to disguise as if it had not been fraudulent. However, even in such a case, it is impossible to disguise the explicit means provided inside the board storage box while restoring it to the original state. You can easily tell whether or not it is.

By setting the area range of the above-mentioned covered state to be the upper part of the ROM provided on the circuit board, the ROM is exposed by releasing the covered state. It is possible to facilitate the work in time.
